Performance and BenchmarksThe L420 is well-stocked with performance components. The second-generation Intel Core i5 processor is more than capable of handling business productivity tasks; 4GB of RAM is enough for multitasking; the integrated Intel HD graphics work fine for everything but gaming. The hard drive is not impressive; the Seagate 7200.4, while it runs at 7200RPM, is old and slower than most modern 5400RPM drives. It is also noisier than newer drives.
